I just received the 1 Meg Agnus today.  I purchased it from Grapevine
(I know I have been warned, but I couldn't resist.)  First thing I did
was verify that the chip was the correct model number.  Yup.  8372A

Many here have horror stories about defective chips, so I popped it in
without making the motherboard modifications.  Well.  It works just as
well as the old one.  SysInfo 2.70 says it's the ECS Agnus too.  But the
program lost some of its credibility when since it also says I have the
ECS Denise.  I don't I'm afraid.

Now for the fun stuff.  I'm trying to read Grapevine's instructions.
Someone said it was a cheap photocopy.  That's much too generous.  It's
a photocopy of a photocopy of a photocopy...  I can read most of it.

The heck with these foolish instructions.  There's somebody out in net
land infinitely smarter who can verify the what I've got to do for
my Rev5 A500:
  o cut trace between middle and lower pads on JP2
  o make trace between top and middle pads on JP2 using soldering pencil
  o bend pin 38 (whichever one that is I dunno) of Gary chip up

I think this is all it takes.  I wont make the modifications until
someone in the know can verify this is what it takes and/or tell me the
proper modification instructions.
